BARTENFELD, OF LOZRAIN, OHIO CHANNELconsrnuc'rron ron BULKHEAIDS This invention relates to channelconstruction for bulk heads, andhas for its main 0bject to provide abulk head which is constructed of standard. steel channels to eliminatetheme of the usualtransverse stiifeners.

Another object of the invention is to provide abulk head constructed ofstandard steel channels arranged vertically in staggered sets with theirflanges extending inwardly and transverse plates arranged between saidsets.

bulkhead is constructed of standard steel channels 4: and .5, whi'charearranged 'ver tically in sets in spaced and staggered relation withtheir flanges indicated'by 6 extending inwardly and connected'togetherby rivets as at 7. Plates indicated by8 are ar ranged between the setsof channels, and the flanges of the end channels are connected to saidplates by rivets 9. The vertical and transverse plates 8' may be of anysuitable width to give thedesired rigidity to the bulk A further objectof the invention is to pro .their upper ends and also their-lower endsbeing in alignment. The lower ends of the channels 4:. are riveted, asindicated at l3,to a plate 14, which is out at its lower edge 15 toconform to the camber, of the tank top 2, to which it is connectedbymeass of an angle bar 16. A vertical angle clip 17 connects "the end ofthe plate 14 to the outer shell 1 of the vessel. The lower ends of thechannels are similarlyconnected to the tank top by aplate 18 and anangle bar 19. The plates 14 and 18 have'upper'inturned flanges 20 and:21 extending between the sets of channels for strengthening saidplates. Angle clips 22 are employed to connect the lower ends of thetransverse and vertical plates 8 to the tank top. 2. Thealternatingrecesses or pockets 23 and 24; formed by the sets of channels 45 and thevertical plates 8 and the longitudinal plates 14.18 are preferablyfilled with concrete indicated by 25' which slopes asshown at 26 toinsure coal,- grain and similar cargoes sliding therefrom.

The upper ends of the channels 4 and 5 are riveted as indicated at 27 tolongitudinal plates 28 and 29, which are cut at their up per edges 30 toconform to the camber of the deck 3 of the vessel, and said plates arefixed thereto by longitudinal angle bars 31 and 32. A Vertical angleclip 33 connects each end of the longitudinal plate 28 to the outershell of the vessel. Angle clips 34 con: nect the upper ends of thetransverse and vertical plates 8 to the deck 8. r

In the modification, Figs. 8 and 9, the vertical channels 35 and 36 areconnected to short longitudinal plates 37' and 38 instead of thelongitudinal plates 14 "and 18, and short longitudinal angle bars 39 and40 con-v nect said plates to the tanktop; By this construction thealternating pockets 23 and 24aof the first described construction .areentirely open at their rear and forward sides.

Similar short plates and angle bars connect 'the upper ends of thechannels 35 and 36 to the deckofthe vessel. From the drawings anddescription, it

will be seen that a bulkheadthus constructed "of standard steel channelsand transverse 'iplates' is rigid due to the flanges of the channelsserving as stiflening means withoutthe *use of transverse stifieners,that this. con- "struction permits varying the rigidity. of the I thetank top, and to the deck of the vessel.

Although-the construction set'forth is for bulk head by employinggreater or less widths of transverse plates, and that thisbulk head isreadily fitted between and connected to the outer shells or side tanks,to

a transverse bulkhead and is well adapted to'accomplish the intendedpurposes, it will be understood that said construction may apply to a'longitudinal bulk head, and that slight changes in the details ofconstruction may be made within the scope of the claims. Having fullydescribed my invention,

what I claim is:-
